Stone dust has lesser fraction of soil passing 0.075 mm sieve and is non-plastic in nature. This helps to improve the gradation and plasticity of the soil when mixed with stone dust. Stone Dust consists of angular particles having more interlocking strength which improves the density of the soil when mixed with stone dust.
